[0020] See Figures 1 to 5 A steel structure for a covered sports field canopy includes: a main canopy 100 and a secondary canopy 200; wherein, The main canopy 100 includes multiple first support columns 1, multiple arched first trusses 2, and a first canopy film 7 covering the first trusses 2; the multiple first support columns 1 are arranged in two rows and spaced apart along the length of the main canopy 100, and the top of the first support column 1 is connected to both ends of the first truss 2 respectively using a first rigid connection node 300. The secondary canopy 200 includes multiple second support columns 5, multiple arched second trusses 3, and a second canopy film 8 covering the second trusses 3; the multiple second support columns 5 are arranged in two rows and spaced apart along the length of the main canopy 100; the top of the second support columns 5 is connected to both ends of the second trusses 3 by a second rigid connection node; the secondary canopy 200 is smaller than the main canopy 100 in the length direction. The main canopy 100 and the secondary canopy 200 are arranged parallel to each other along the length direction. The first support column 1 and the second support column 5 at the adjacent long sides of the main canopy 100 and the secondary canopy 200 share the same common support column 4. The top of the common support column 4 is connected to the first truss 2 and the second truss 3 through a shared rigid connection node with two connectors to form two connected arch structures.

[0021] The main canopy 100 and the secondary canopy 200 share a common support column 4, which reduces the number of independent support columns, thereby reducing steel consumption and foundation construction costs. The main and secondary canopies 200 are set up in parallel and side by side, sharing the support columns on adjacent long sides, which simplifies the layout and improves the efficiency of space utilization.

[0022] The arched trusses of the main canopy 100 and the secondary canopy 200 are connected at the top of the common support column 4 through a shared rigid connection node (not labeled in the figure), forming a double arch structure. The axial pressure of the double arch dominates the force transmission mode, reducing bending moment deformation, while dispersing the horizontal load and avoiding overloading of the structure on one side.

[0023] Specifically, the secondary canopy 200 protrudes from the main canopy 100 at one end in the length direction. At the long side of the secondary canopy 200 adjacent to the main canopy 100, a portion of the second support column 5 shares the same common support column 4 with the first support column 1. The portion of the second support column 5 protruding from the main canopy 100 independently supports the second truss 3.

[0024] With the protruding section design, the secondary canopy 200 can cover areas that the main canopy 100 cannot extend to, expanding the coverage and flexibly adapting to the site; the independent support columns of the protruding section work together with the common support columns to avoid overloading of the common support columns 4 due to the cantilever structure, ensuring overall stability.

[0025] More specifically, the bottom of the first support column 1 and the second support column 5 also includes a fixed node 400 connected to the court surface. The fixed node 400 includes an anchor plate 402 connected to the first support column 1, the second support column 5 and the common support column 4, and several L-shaped anchor bolts 401. The L-shaped anchor bolts 401 are embedded in the concrete foundation piles 404 of the court. The horizontal section of the L-shaped anchor bolt 401 is embedded in the concrete, and the vertical section of the L-shaped anchor bolt 401 extends upward through the concrete surface. The anchor plate 402 also has bolt holes corresponding to the L-shaped anchor bolts 401. The vertical section passes through the anchor plate 402 and is fastened by double nuts 403.

[0026] The L-shaped anchor bolt 401 utilizes the friction and mechanical interlocking force between the horizontal section and the concrete; when the vertical section of the bolt is under tension, the "anchoring effect" of the horizontal section prevents it from being pulled out. The L-shaped anchor bolt 401 is locked with double nuts 403, and welded after being locked with double nuts 403, which can effectively prevent loosening and thus meet the anti-overturning requirements in high wind environments.

[0027] Preferably, water guide channels 9 are provided on both sides of the first truss 2 and on both sides of the second truss 3.

[0028] Specifically, it also includes a downpipe 10 that matches the water guide channel 9.

[0029] Directly installed on both sides of the truss, rainwater naturally flows along the surface of the canopy membrane into the drainage channel 9, avoiding water accumulation and reducing the risk of steel structure corrosion. The downpipe 10 is seamlessly connected to the drainage channel 9, quickly guiding rainwater to the underground pipe network and preventing overflow from washing away the court surface during heavy rain.

[0030] Preferably, each of the first rigid connection node 300, the second rigid connection node, and the common rigid connection node includes: at least one connector and a connection plate assembly; The connector includes a first connecting flange 301 and a second connecting flange 302 that are vertically arranged and connected to each other. The first connecting flange 301 and the second connecting flange 302 are connected by a bolt pair 306 and have mounting holes for mounting the bolt pair 306. The first connecting flange 301 is used to connect to one side of the arch of the first truss 2 or the second truss 3, and the second connecting flange 302 is connected to the connecting plate assembly. The connecting plate assembly includes a vertical connecting plate 307 and a horizontal connecting plate. The horizontal connecting plate includes a first horizontal connecting plate 304 and a second horizontal connecting plate, which are parallel to and spaced apart along the height direction of the first support column 1, the second support column 5, and the common support column 4. The second horizontal connecting plate is disposed on the plane of the column head of the first support column 1, the second support column 5, and the common support column 4. The first horizontal connecting plate 304 is higher than the second horizontal connecting plate, and the first horizontal connecting plate 304 and the second horizontal connecting plate are connected to the first side of the second connecting flange 302. The vertical connecting plate 307 is connected to the first horizontal connecting plate 304 and the second horizontal connecting plate 303, and is disposed on the second side of the second connecting flange 302. The first side is the flange plane, and the second side is a side perpendicular to the flange plane.

[0031] The first horizontal connecting plate 304 and the second horizontal connecting plate 303 are arranged parallel to each other to form a rigid sandwich structure, which disperses the bending moment and shear force at the ends of the truss, reduces local stress concentration, and improves the stiffness of the nodes. The paired first connecting flange 301 and second connecting flange 302 are locked by bolt pair 306 to evenly transfer the axial force and lateral force of the truss to the support column and avoid overloading of the connecting plate on one side.

[0032] Preferably, the connecting plate assembly further includes a reinforcing rib 305, which is disposed within the space formed by the first horizontal connecting plate 304, the second horizontal connecting plate 303, the vertical connecting plate 307, and the second connecting flange 302; one end of the reinforcing rib 305 is connected to the first horizontal connecting plate 304, and the other end is connected to the second horizontal connecting plate 303, so that the space formed by the connecting plate assembly is divided by the reinforcing rib 305.

[0033] The reinforcing rib 305, located between the first horizontal connecting plate 304 and the second horizontal connecting plate 303, disperses shear force through a triangular stabilizing configuration, thereby improving the shear bearing capacity of the joint and suppressing the risk of weld cracking in the connecting plates. The reinforcing rib 305 vertically connects the two layers of horizontal connecting plates, constrains the relative displacement of the horizontal connecting plates, improves the bending stiffness of the joint, and reduces fatigue damage under alternating loads.

[0034] More specifically, the arched tops of the first truss 2 and the second truss 3 are provided with a number of purlins 6 at intervals, and the length direction of the purlins 6 is parallel to the length direction of the first truss 2 and the second truss 3.

[0035] Roof purlins 6 are set at equal intervals along the top of the arched truss to evenly distribute the local load of the canopy membrane (such as wind pressure and snow accumulation) to multiple trusses, avoid overloading of individual trusses, and improve the overall rigidity of the structure.

[0036] It should be understood that the above description of the specific embodiments of this utility model is only for illustrating the technical route and features of this utility model, and its purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. However, this utility model is not limited to the specific embodiments described above.
